TRACK-CLAMP.

SPECIFICATION forming part of Letters Patent No. 477,943, dated June 28,1892.

Application filed March 3, 1892. Serial No. 423,633. (No model.)

marked thereon, which form a part of thisspecification.

This invention relates to improvements in clamps for railway-rails.

The object of the invention is to provide means for connecting the railsto each other to prevent them spreading; and it consists in theconstruction and combination of the parts, as will be hereinafter fullyset forth, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figurel is a sectional view showing the device applied. Fig. 2 is aperspective view, partly in section, showing the parts which make up theclamp detached. Fig. 3 is a perspective view showing the inventionapplied to a rail-joint having a fish-plate.

A designates a rod, the ends of which are threaded either in. the sameor reverse direction, as may be preferred, and these screwthreadedportions a ct may be of a greater diameter than the rest of the rod orof the same or less diameter, a larger diameter being preferred for thereason that the parts of the upon the center portion of the rod whendesired.

B and B designate adjustable clamp-nuts, which have central apertures hand b', a portion of each of which is enlarged, as shown, the reducedportion of each aperture being screw-threaded to receive the threadedends of the rod A. Each clamp-nut has an annular shoulder c, which isadapted to engage with one of the clamping-heads which embrace thebase-liange of the rail. The eX- tended portion of the clamp-nut Bisexternally screw-threaded, as shown at d, for engagement with thethreads d', formed in the enlarged portion ot' the aperture in the clampnut B.

D and D designate the clamping-heads, which have jaws c and e', whichare adapted to engage with the base-ange of the rail. The clamp D has anaperture f, which is adapted to tit over the unthreaded portion ot' theclamp-nut B adjacent to the shoulder c, and beyond this aperture f is arecess or aperture g of larger diameter, into which may pass the innerend of theclamp-nutB. y The clamp D is provided with a straight-awayaperture f', into which passes the inner end of the clamp-nut B', and,if desired, the under side of the clamp may be cut away, so that it canbe readily placed over the rod A, as it may be necessary to remove saidclamp and replace it with one having a jaw of a different size forengagement with a sh-plate, as shown in Fig. 3.

' The device hereinbefore described is adapted to be applied to therails between the ties,

and it will be observed that the fixtures at end of the rod A areindependently adjustable, so that the rails may be adjusted to theproper gage.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, in a clamp for railwayrails, of a rod havingthreaded ends, clampnuts threaded for engagement therewith and with eachother, and clamping-heads apertured for the passage of the clam p-nuts,said heads having jaws, substantially as shown, and for the purpose setforth.

2. The combination, in a clamp for railwayrails, of a rod A, anadjustable clamp-nut adapted to engage with the threaded portion of therod, and a head having j aws,'and a portion which encircles theclamp-nut, said encircling portion being cut away to provide for placingthe same upon-the rod, substantially as shown, and for the purpose setforth.

3. The combination, with a rod A, having threaded ends, of clamp-nutsBand B', threaded for engagement with each other and provided withshoulders c c, and clamps D and D', apertured for the passage of theclamp-nuts, the shoulders c c of the clamp-nuts bearing IOO against theouter edges of the clamps, substantiailyras shown, and for the purposesety forth.

4. In a rail-clamp, the combination of a rod 5 having a threaded end, anadjustable clampnut threaded for engagement therewith and provided Witha shoulder c andan inwardlyextending portion, a clamp carrying jaws andprovided with an aperture through-Which the 3 [c inwardly-projectingportion of the Clamp-nut passes, the shoulderc thereof bearing againstthe exterior portion of the clamp adjacent to said aperture,substantially as shown.

In testimony whereof I afx my signature in presence of two Witnesses.
